Roku 3 wifi connection issues

Hi,

I have 2 Roku 3 devices in 2 rooms connected by wifi, and a Plex sever connected by wires. Recently the Roku furthest away from the router really struggles for a wifi signal so I moved it a bit closer, which has helped but not fixed it. The other Roku is in a unit underneath the router, literally half a meter away and that one struggles too. I've bought a network switch so I can wire it in, but I wanted to see if anyone has any ideas as to why this has started to happen recently? Nothing changed in my network setup and sometimes the Roku under the router can't stream Plex at all, and Netflix looks like it's running at 480 or something. They've both been fine for years.

Thanks.

Re: Roku 3 wifi connection issues

1) Your router can be configured to use several different wifi channels.  Interference from other nearby systems using the same channel can seriously degrade wifi performance. You may have had a neighboring system start up, or change the channel it uses, and start interfering with your system.  Experiment with configuring your router to use a different wifi channel to see if you can improve performance.  There are apps you can install on your phone to help you find channels with less intrference.

2) It is actually possible to be too close to the router such that the signal is too strong and overwhelms the Roku's wifi receiver.
